How do I swap the dimensions of a 3D matrix?

For example, I have a 3D array A so that size(A) = [5, 2, 20]; How could I make it like [20, 2, 5] or [2, 5, 20], any order?

Edit: I didn't make it clear initially. A is 3-D, like a dice, I don't want to cut the dice and rearrange the data, instead I just want to roll the dice, so that I'm looking at this same dice just from a different angle.

permute(A, [3 2 1])
